Don't waste your money. ( unless you want something for by the toilet) Its all here. All the latest products and techniques being utilized in real time with the best genetics available on the planet. If your bent on getting one start old school, get Marijuana Botany, by Robert Clarke. I had a copy when I was 14.
You probably dont have the updated version then. RCC released a revised edition in 2010.
I always recommend Marijauna Botany by Robert C Clarke though, It really has the most information your going to need. Another good one is Jorge Cervantes Ultimate grow guide, The learning curve on it is pretty quick etc but it has a lot of good reference points in it. Its also a lot quicker then running back to your computer to look something up...
What will make you a good pot grower is...
Persistence. Now book can give you that.
But always go back and read the book when you dont know something
When the book cant answer it come to good ol' THCfarmer and look around
When Good ol' THCFarmer doesnt have the answer just ask the farmers :D
When the farmers dont have the answer, its time to do an experiment and share it with your fellow farmers.
Books do Have a need, who ever says that don't probably ask a lot of questions about burn(I think its embarrassing)
